10. The role of bile acids in the reduction in lipopolysaccharide uptake by cultured rat Kupffer cells.

Abstract

The influence of bile salts on the binding and uptake of Salmonella abortus equi lipopolysaccharide by cultured Kupffer cells was studied. In control preparations, the percentage of cell-associated lipopolysaccharide increased with time and reached a plateau after about 2 h incubation at 37° C. About 1.2 μg lipopolysaccharide was associated with 10 Kupffer cells at this time interval. In the presence of 0.3, 0.6 and 1 μmol bile salts/ml the cell-associated lipopolysaccharide was respectively, about 5%, 13% and 29% lower than in control cultures. In the presence of 1 μmol bile salts/ml, the association of lipopolysaccharide to cells at 0° C was about 25% lower than in controls. Preincubation of Kupffer cells with 1 μmol bile salts/ml, with or without lipopolysaccharide, did not affect cell-associated lipopolysaccharide after removal of the bile salts. The rate of secretion of radioactivity by Kupffer cells was not influenced by the presence of bile salts during the uptake or the secretion periods. Bile acids proved to inactivate lipopolysaccharide. From these observations it was concluded that low concentrations of bile salts influence the binding and uptake of lipopolysaccharide by Kupffer cells. It was, therefore, considered likely that, in patients with obstructive jaundice, the high serum bile acid level accounts for spill-over of portal lipopolysaccharide into the systemic blood.
